e*thirteen 10 and 11-Speed Wide Range Cassette - 2016 Mountain Bike Components at Eurobike - Mountain Biking Pictures - Vital MTB

e*thirteen's cassette is no longer just a prototype and is moving into production. The cassette offers a very wide range with a 9-44 tooth spread on their 11-speed cassette, and a 9-42 tooth on the 10-speed version.

Due to the low 9-tooth count they had to get clever with the design. The multiple piece cassette includes two assemblies. The back assembly is machined from aluminum and includes either three or two gears depending on which speed setup you're using. This locks onto a SRAM XD driver body.

The remaining eight gears lock on using a chain whip. The front cluster is the same between both the 10- and 11-speed cassettes though the back cluster changes. e*thirteen uses a smaller cluster made from heat treated steel which is then machined to achieve the lightest weight possible. The use of steel improves longevity and durability. e*thirteen will sell this for $300 US, saving you quite a few $$$ over the leading competitor.

    OK....main question: Is a 44t chain ring actually bigger than a 180mm disc?

    It's an expensive cassette, but no more so than a XX1, and 9-44 would pretty much be an ideal 11 speed setup if the steps between the cogs aren't too abrupt. It would have an 489% range, meaning if you a ran a 30t chain ring and this cassette you'd essentially have the same range as someone running a 36/24 double with a 11/36 cassette. E13 have a winner on their hands if the chain wrap on the 9 tooth cog works out and the overall wear rate is reasonable. Make the aluminum portion of the cassette available separately as a replacement part and its a home run!

    $300 for cassette!!!! My bike was only £280 and it gets me up and down all the trails in the Peak District. I would understand the price of it was for a high tech peice of suspension but it's just a bit of steel and steels cheap

    It is very tough to get enough chain wrap on 9T cogs. I suspect that contributed to why the aftermarket Canfield 9T (which was first released 5+ years ago) never really took off.

    I'm sure you can get them to work great in the stand, under max power though is another story...

    I have a friend who runs the Canfield on his new Turner 27.5 and I have a Leonardi 942 and neither one of us have any issues with the 9t under power. I don't think they ever got big because not a lot of people knew they existed. When a bigger company makes these and enough people can see the benefit of a real wide range cassette, they will take off.

    I mean a lot of power...

    Seriously though, that has been an issue and Canfield is well aware of it. On a DH or Road cassette with a 28T max cog it could very well be less of an issue. To get enough chain wrap on the 9T you really have to back off the B Tension adjustment. To the point that you then do not have enough B Tension to effectively move up to your 34T or 36T low gear (obviously I'm talking about 10 spd applications.)

    That might be an issue with a Shimano derailleur, but Sram handles it just fine. I've had two 9-42 10 speed cassettes both with a med cage XX derailleur and no issues for almost 2years. And the range u get is awesome.

    Yeah Zo, I think that was the case in the years of old but the offset pulley situation of SRAM/Shimano 11sp and the popular Rad cage for Shimano 10sp wide range applications seems to correct that issue. Subtle improvements to the rear derailleur over the years make it look the same as it's always been but a lot's changed in those 5+ years. I think Shimano had just embraced limited B tension (i.e. shadow) and clutches/offset pulleys were still a ways off back then.

    Really coucciano? Why did you call yourself PVFlier when you know it's PV couch layer. Go take a Motrin and lay back down on the couch before you hurt yourself biotech!.

    That could very well be the case.

    using XD freehub? Same concept as SRAM?

  • Faster Than U

    8/27/2015 9:57 PM

    You have to use the XD to fit the 9t cog. The Leonardi 9-42 also uses the XD driver

    Looks cool, but what do they weigh? The Leonardi 9-42 works great and only weighs 250g.

    Leonardi weighs 315g in 11s. Anybody know the weight of this E-thirteen in 11s?
